Dial Mill is a historic gristmill and flour mill outside of Conyers, Georgia. It was added to the National Register of Historic Places on April 6, 1977. The mill is a three-story frame building but as tall as a modern five-story building. It is made of hand-hewn virgin pine, with sixteen-inch square interior beams. It has a one-story shed addition on the north side and an overhanging roof at first-floor level around the west and south sides. The building has flour and corn milling equipment "with shuts and grain elevators containing an intricate system of belts and pulleys which carried grain from floor to floor during the milling process."
